SOURCE: 02 GCL tranny problem

The transmission in your vehicle is a 5-45RFE model.Check,or have the fluid level checked.I would have the vehicle scanned for trouble codes,and with the scan tool,there is a feature in the data stream called "clutch volume indexes".I always look at those to determine clutch pack wear as a tool to evaluate the condition of the individual clutch packs inside the trans.A way to look inside the trans without removing a single bolt.Backing up to the codes,if there are any,thats the direction the repair will go unless the "cvi"'s indicate otherwise.I have seen shorted out O2 sensors cause transmission shift problems as you had described,but the trans always went back to normal operation after the O2's were repaired/replaced.The solenoid packs i replace with every rebuild, with a remanufactured unit as they are prone to problems also.It is possible to replace the solenoid pack without a rebuild too.The solenoid assembly is located on the valve body,just inside the trans pan.

As I said, trans fluid keeps the internal components "alive"... Low fluid level can cause burning of internal clutches, premature hardening of seals (essential to proper transmission of fluid pressure) as well as lubrication of necessary gear components such as planetary gear set (which can cause whine etc. which you now have) All of these components rely upon a constant flow of fluid for both cooling and lubrication. Depending upon how low and how long these parts had interrupted fluid flow, directly influences how much damage was done. I take no joy in telling you that you may have damaged your unit, I'd be far happier if I could give you a quick, inexpensive fix. But based upon what you have said, If I was working hands-on with this problem, I would make the recommendation I've already made. There are pressure tests etc that can be done at a transmission shop to verify to some degree of certainty what is going on within your unit. Hopefully they may find something other than what I've said. At this point though, it is wise to have it checked out by a professional, before you become stranded at a time when you can least afford to be.

SOURCE: Will a 1996 5.2L V8 jgc tranny bolt into a 1996 4.0L I-6 jgc?

To the best of my knowledge they never put a 44Re behind the 4.0
If you are looking to upgrade, you could use some componets from the 44Re and install them in your 42Re case...The front, overdrive and direct clutch packs, each have one more disc....All other specs appear to be the same.
Note: The PCM for the 4.0 is programmed for the factory installed transmission.
Hope this helps...

700 is generic code meaning a transmission malfunction. It could electrical or mechanical. You'll have to retrieve the other codes. The solenoid packs are the most common parts replaced on these.

2006 5.7 545rfe trans. Last wed replaced solenoid block pack. Went great wed, thurs but friday morning got po700 and po876 code and has gone in limp mode. Any suggestions? Please help

Possible front transmission pump getting bad. This will also cause accelerated wear on the clutch packs. Talk to your local Tranny repair shop for advice. The solenoid/pressure switch assembly you changed relies on pump pressure for its operation.

I have a 06 Ford F-150 4X4 that has codes po731, po732, and p1000, which is sluggish on acceleration and has no overdrive. Any ideas?

The po700 codes are transmission related ( turbine codes ) if I recall. Usually the tranny control module will put the tranny in 2nd gear which will give you the sluggish feeling. I would suggest having a tranny pro look into this and isolate the problem for you

2005 pt cruiser,2.4 automatic would not shift out of first. codes 0700 & 0733. replaced solenoid pack, speed sensors. did fine till stop & go travel tripped engine light, would not change out of...

You go to a qualified transmission shop and let an experienced technician diagnose and repair the problem. (Unless you can read and understand all the codes from your TCM, and have the equipment to check fluid pressures at all the test ports)
Resetting the check engine light is obviously not correcting the problem - it comes back as soon as you get into stop and go traffic. Your transmission is going into limp mode, which is what it's supposed to do. Just enough to allow you to get it to a shop and get it repaired. Continuing to drive it this way may do further damage to the transmission. What may now be a fairly inexpensive fix (sensor, solenoid, etc), may become a very expensive fix.

Transmission going into limp mode. Have changed fluid and filter, went 300 miles and back to limp mode. Had a gas cap that wasn't the correct one so I just bought a new one. getting codes po456, 442,...

Change your input/and output speed sensors, check your fluid level in the tranny, test cam sensor. If problem still occurs then check the tranny solenoid pack and replace as needed. It is important to understand that in MOST cases, the plug in connectors to these sensors are worn and the plastic part of the plugs expand when the engine warms up and then the proper connections are lost. MOST of the time a sensor works fine but either the wire OR the connector itself is not working. Always check these connections first as most of the time this is EXACTLY what your problem may be and your repair is free!
